R wrapper for 4SAIL model

1	foursail(refl, tran, rsoil, param)

`refl`	input leaf reflectance from 400-2500nm (can be measured or modeled)
`tran`	input leaf transmittance from 400-2500nm (can be measured or modeled)
`rsoil`	input soil reflectance spectra from 400-2500nm (can be measured or modeled)
`param`	Vector of SAIL parameter values: * LIDFa: Leaf angle distribution function - parameter a * LIDFb: Leaf angle distribution function - parameter b * TypeLIDF: Leaf angle distribution function type (1 or 2) * LAI: Leaf area index * q: Hot spot effect parameter * tts: Solar zenith angle * tto: Observer zenith angle * psi: Sun-sensor azimuth angle

Spectra matrix (see spectra()) (2101 x 4) of reflectance factors for wavelengths 400 to 2500nm: * bi-hemispherical reflectance (rddt) * hemispherical directional (rsdt) * directional hemispherical (rdot) * bi-directional (rsot)
